SIGNALING DEVICE.

Specification of Letters Patent.

Application filed January 19, 1910. Serial No. 538,815.

To all whom it may concern:

Be it known that I, HENRY BERGONZINI, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Signaling Devices,

' of which the following is a full, clear, and

Another object thereof is to provide j device of this character whichmay be easily attached toany suit-able frame, readily ad; ,justed inposition and in which the electric connections may be quickly andpositively made.

Other. objects will bein' part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features ,of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter setforth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings, wherein 15 shown one of various possibleembodiments of thisinvention,Figure 1 is a diagrammatic side view of anautomobile showing the signaling device attached thereto; Fig; 2 is aside elevation partly in section, of the signaling lxdevice, the sectionbeing taken on line wa;i of Fig. 3. Fig. 3 is a front view of thediaphragm casing with the cover and diaphragm removed; Fig. 4 is aplanview of the motor casing showing the means employed to vibrate thediaphragm, parts. being in section 5 Fig. 5 is a perspective view of acrank dlsk and cam'adapted to drive the vibrator; Fig.' 6 is'a detailview partly in section of the-vibrator and associated parts: Fig. Tie asectional view of a socket adapted to complete the elect-ric "circuitthrough'the motor; Figs. 8 and 9 are interior views of.

thetwo halvesof the :socket; Fig. 10 is an Motor pole pieces 25 may beformed as part end view of the parts shown inFig. 6.

Similar reference numerals refer to simia lar parts throughout theseveral views. Now referring to the drawings, 1 indicates a casingadapted to inclose the motor and secured to this casing is a secondcasing 1 adapted to contain the means used to pro duce vibration of thediaphragm 2. While in the present form, the casings l and l" areintegral with one another, it is obvious that they may be made separateand secured together in any manner desired, without departing from thespirit of this invention The casing 1 is provided with a tubular arm 3whichterminates in a socket member 4.

Upon a reduced portion of the arm 3 a bracket 5 is adapted to swivel andto be Patented Apr. 2a, 1913.

tightened thereon by means of a thumbscrew 6. In Fig. l the casing isshown as secured to the frame of an automobile by means of The leadsfromthe motor are fastened to contact members 7 in the socket member 4,these contact members being supportion thereof, thesocket member 4 ofthecasing. The two membersare s cured to: gether by means of a bayonetjointf'c'o'mpris- ,ing a pin 1.4 and an angular slojtfl15. The

wires 16 from-the battery are secured to two contact members 17 disposedwithin and in; sulated from the socket member 13 in such manner thatwhen the socket members are locked together the contact'mernb'rs of" theone part will engage the contact members of the other part and completethe electric circuit to the motor. v

The casing 1 is provided" adjacent one end of the motor armature 18Ywith acap l9 providing an end bearing f'onthearmature shaft .20; Theother end. oaths" armature shaft has ita bearing in the wall'21 of thecasing 1, through which it extendspto have secured thereto a crank disk22* provided with a crankpin. 23, and carrying upon its outer surface; acam .member'Q i, the object of which 'will be hereinafter described.

of easing 1 and the field coils 26 placed thereon in the usual manner.The brush holders 27 are supported'by a fiber insulat ing' ring 28 a andthe brushes are forced against the commutator in any 'suitable manner.The casing 1 extends beyond the walls of the motor casing 1 and providesan annular flange 29 threaded'upon its outer circumference andsurrounding a space 30 within which the crank disk 22 rotates. A cap 31is provided with a flange 32 interiorly threaded to engage with thethreads on flange 29, which upon being screwed thereon serves to clamptherebetween theresilient diaphragm 2. Located in the center of the saiddiaphragm and secured to the inner side thereof, is a projecting member'33 providing two abutments 34 and 35. A horn or resonator 36 of anydesired construction fits securely over a forward projection 37 of thecap 31; Extending in-- wardly from the inner circumference of the;

flange 29, are two lugs 38 which are formed to serve as one side of aguide, of which the other side comprises two similar members 39, securedto the casing 1 by means of screws 40. Between these guides a slidingmember 41 is adapted to reciprocate, the

motion thereof being in a plane substg;

tially parallel to the plane of the diaphra 2. At about the center ofthe saidslide extends a transverse member'42 which is provided with aslot 42 as shown in F ig. 3, adapted to receive the crank pin'23. Uponopposite sides of the slide, adjacent the two ends thereof, slots 43 and44 are provided. Toothed members 45 and 46 are pivoted to the slidewithin these slots, the said members extending longitudinally of theslide upon either side thereof in opposite directions.

an opposite direction to the teeth of the member 46', and that the teethof each member slope away from the pivotal point thereof. Spring members47 secured at the two ends of the slide press upon the top of of thisinvention, the operationthereof,

which is largely obvious, follows: Upon the electric circuit beingclosed at the push-but- It will be seen by reference to Fig. 6 that theteeth of the member 45 are disposed in ton, the motor armature begins torotate, the crank disk 22 rotating therewith. This rotation istransmitted by the crank pin to the slide member 41 as a reciprocatingmotion within the guides. As the slide moves toward the left, as viewedin Figs. 3 and 6,

the toothed member 45 is raised by the cam 24 so that the points of theteeth thereon come into contact with the abutment 35 upon the diaphragm.The contact of each tooth with the abutment produces vibration of thediaphragm, and upon, reversal of the movement of the slide,'the cammoves from beneath the toothed member=45 and into contact with thetoothed member 46, permitting the former to drop and raising the latterinto contact with the diaphragm abutment 34, whereupon the diaphragm isvibrated by the latter member and as the teeth of one member arespacedrelatively to the teeth of the other member so as to produce theeffect of a continuous, uniformly toothed surface, the vibration ofthediaphragm is continuous and uniform. While any motor speed or numberof teeth may be employed, the best results'have been obtained by using aseries motor adapted to runat about 3,500 revolutions per minute whentaking current from a source, having a difference of potential of-vabout eight volts. Ten teeth are PIOXldGd, giving the number ofdiaphragm impulses as 35,000 per. minute. At this rate of vibration thediaphragm gives forth tones adapted to effectively alarm those for whomthe warn ing is intended. Thediaphragm may be spaced nearer to orfarther away from the toothed members by inserting suitable washersbetween the same and the casing. It .Will accordingly be seen thatherein is provided an apparatus well adapted to attain, among others,all the objects and ends above pointed out in an exceedingly simple yetefiicient manner. The motor, reciprocatingmechanism and electric wiring,all being inclosed are well protected from the effects of bad weatherconditions and because of the form of the vibrating mechanism a verycompact construction is made possible of attainment. It should be notedthat when the current is shut off, the motor will. stop approximatelyupon the nearestdead-center of the reciprocating device, thus, almostimmediately stopping the sounding of the alarm.

As many changes could be made in the;

above construction and many; apparently widely-different embodiments ofthis invention could be made without'departing from... the scopethereof, it, is intended that all matter contained in the abovedescription or shownin the accompanying drawings shall be interpretedasillustrartive and not 'in a limiting sense. It is also to'be.understood that the language used in the follow. ing claims is intendedto cover all of the combination, a horn or-resonator, a diageneric andspecific features of the invention herein described and; all statementsof: the scope of the invention, which, as a matter of language, might besaid to fallthere between. 1
